Crude Oil
- Tiny sea plants and animals died
and buried on the ocean floor.
- Deeper and deeper. The
enormous pressure and
heat turn them into oil
and gas.
- They didn’t completely
decompose because there
wasn’t enough oxygen in the
water. Over time, they were
covered by layers of sediments
and rocks.
- Over millions of years, the
remainds where buried
- Today, we drill down throught
the layers of sedimentary rock
that contains oil and gas
deposit.
- NON-RENEWABLE SOURCES
OF ENERGY
- OIL IS A MIXTURE OF DIFFERENT
HYDROCARBON MOLECULES. AND
WHEN WE SEPARATE THEM WE OBTAIN
DIFFERENT PRODUCTS.
- To separete molecules of different
lenghts, we pass oil throught a HOT
PIPE. As the OIL GETS HOT, the
LIGHTER MOLECULES EVAPORATE
and exit the pipe. As the OIL GETS
HOTTER, the HEAVIER MOLECULES
EVAPORATE and exit the pipe.
- OIL IS A MIXTURE OF DIFFERENT
HYDROCARBON MOLECULES. AND
WHEN WE SEPARATE THEM WE OBTAIN
DIFFERENT PRODUCTS.
